Abstract

The utility model provides a rotary shaft combined fixing structure which mainly comprises a shaft rod, a connecting piece and a torque force assembly, wherein the shaft rod is provided with a fixed part and a shaft body along a shaft center direction. The connecting piece is composed of a vertically arranged shaft seat and a locking body. The torque force assembly is penetrated by the shaft rod in a shaft connection mode. A shim is engaged and fixedly connected with the shaft body in a matching mode by the means that the shim is provided with multi-angle pawl holes. The shaft body is directly riveted on the shim for generating compression action to the torque force assembly. Thus, the components can be tightly contacted. Because the shaft body adopts a riveting mode to tighten the torque force assembly, good torsion force action is generated within the range limited by the shaft body.

Description

Rotating shaft combination fixed structure

Technical field

The utility model relates to a kind of rotating shaft combination fixed structure, is meant that especially the most easy integrated mode of utilization reaches and has good combining closely, to obtain the rotating shaft combination fixed structure that preferable height rotates torsion.

Background technique

As shown in Figure 1, it is known turning gear, this device is applied to the screen and the main frame body joint of mobile computer mostly, can interconnect between screen and the main frame body and function in relative rotation to reach, and the rotating shaft that generally can change screen elevation angle degree need have higher torsion, and therefore good turning gear can provide and have good hinge function.

Among the figure, this axostylus axostyle 1 ' form 3 for be connected with torsion with its axis body 11 ' run through ' and be located in link 2 ' on, axis body 11 ' end impose packing assembly 31 ', by packing assembly 31 ' along axis body 11 ' axis direction gradually to link 2 ' sealed approaching, reach with torsion form 3 ' oppress mutually and be anchored on axostylus axostyle 1 ' on.Yet, with packing assembly 31 ' with axis body 11 ' screw togather mutually interlocking, though torsion can be formed 3 ' packing, but because after the regular hinge of turning gear uses, axis body 11 ' just get loose easily, slide with packing assembly 31 ' interlocking place, at this moment torsion is formed 3 ' just and can't be reached the fastening effect of compressing, and this also will make torque value reduce, and with the location influence is greatly arranged all for the fixed angle that starts of screen.

In addition, because conventional construction is to make torsion form 3 ' fastening effect with packing assembly 31 ' reach, but because packing assembly 31 ' have certain thickness and a volume, therefore its space of rotating shaft setting is provided is necessary increase, day by day under the trend of miniaturization, these all are must improve and the problem place that overcomes at electronic product.

Summary of the invention

Main purpose of the present utility model gets loose in view of known turning gear uses a period of time to be easy to generate and is difficult for keeping these problems that must improve such as high torque value, studied improvement, thereby provide a kind of rotating shaft combination fixed structure that can keep high torque value, it adopts the riveted packing by torsion being formed run through with axis body after being provided with, making torsion form to be pressed compels to close on axis body, and each inter-module is able to mutually closely contact, so the torsion composition all can provide good twisting force in the slewing area that axis body limited.

The purpose of this utility model realizes by following technical proposals, rotating shaft combination fixed structure provided by the utility model mainly includes axostylus axostyle, link and torsion and forms, wherein axostylus axostyle is provided with fixing part and axis body along axis direction, this link is made of a vertically disposed axle bed and interlocking body, the axis hole top of axle bed has a short slot, torsion is formed and to be included friction component, location piece and pad, and it is run through by axostylus axostyle all to be coupling; It is characterized in that: axostylus axostyle is to run through the torsion that is coupling with axis body to form, and utilizing pad to have polygonal pawl hole can be affixed with the axis body interlock, and collocation directly is riveting in axis body on the pad, as producing torsion is formed contention effect, makes each inter-module closely to contact.

Relevant for the utility model be achieve the above object, technological means and effect thereof that feature adopted, exemplify preferred embodiment now and conjunction with figs. is described as follows.

Embodiment

See also Fig. 2 to shown in Figure 4, rotating shaft combination fixed structure of the present utility model mainly forms 3 by axostylus axostyle 1, link 2 and torsion, wherein axostylus axostyle 1 is provided with fixing part 11 and axis body 12 along axis direction, this fixing part 11 can be for affixed with product, handing-over mouth 111 one by fixing part 11 are connected with axis body 12, these axis body 12 the inners are provided with location axial region 121 between interface 111 places, 121 one-tenth non-circular shapes of this location axial region give and locate axial region 121 socket fixed positions so part torsion can be formed 3.

This link 2 is made of a vertically disposed axle bed 21 and interlocking body 22, interlocking body 22 can be fixed with product, axle bed 21 is provided with axis hole 211 and axis hole 211 tops have a short slot 212, and axostylus axostyle 1 can pass through behind the axis hole 211 to be formed torsion 3 and run through one by one and be connected on the link 2.

And, two friction components 31 of torsion composition 3 are axis hole 211 places that are arranged at axle bed 21 bi-side respectively, and run through fixing by axis body 12, and the friction component 31 that is provided with in the inboard of axle bed 21 for and be connected to location piece 32, and friction component 31 and location piece 32 give fixed position by the location axial region 121 of axis body 12, can rotate and start with axis body 12; And location piece 32 be able to place between axle bed 21 short slots 212 in outer ledge and along the tongue piece 321 that axostylus axostyle 1 direction is extended, when axostylus axostyle 1 rotates because of object drives, its tongue piece 321 just can be positioned at short slot 212, when therefore axostylus axostyle 1 rotates with respect to link 2, location piece 32 rotates with axostylus axostyle 1 because of frictional force, but only allowing tongue piece 321 because of short slot 212 designs does limited distance and moves in it, so the relative location piece 32 that makes only can be cooked the rotation of several angle with axostylus axostyle 1, limit axostylus axostyle 1 rotation angle person (as shown in Figure 5) to reach.

Axostylus axostyle 1 run through be combined with friction component 31 and location piece 32 after, axis body 12 parts of axostylus axostyle 1 are to be articulated with a pair ofly with contact anchor ring 331 shell fragments 33 of butt joint mutually, and are nested with pad 34 at axis body 12 ends, are coupling on axis body 12 so that torsion is formed 3; And structure of the present utility model be utilize pad 34 to have polygonal pawl hole 341 can be affixed with axis body 12 interlocks, and the collocation directly axis body 12 is riveting on the pad 34, as producing torsion is formed 3 contention effects, make each inter-module closely contact mutually, and can store the elastic-restoring force of reinstatement because of shell fragment 33 distortion that suffers oppression, therefore under preferable situation, when axostylus axostyle 1 relatively rotates on link 2, friction component 31, location piece 32 and pad 34 etc. will rotate with axis body 12.

And because axis body 12 is to adopt in the riveted mode torsion is formed 3 packings, therefore produce twisting force in torsion composition 3 scopes that all axis body 12 is limited again, and can be as conventional construction once the degree that screws togather between nut and axis body when not good, then torsion promptly produces the gap between forming 3, so that influences the hinge function.

In sum; embodiment of the present utility model really can reach the use effect of expection; yet; the above only is preferred embodiment of the present utility model; such as be familiar with equivalence that the personage Fan Yi spirit of the present utility model of skill of the present utility model made and modify or change, all should be encompassed in the claimed claim of the application.
